Evaluation that fosters positive change.

Evaluation Specialists is a woman-and LGBTQ-owned small business. We are based in California, with staff working and living in California, Washington, and Colorado. We provide comprehensive evaluation and research services. Our goal is to support learning and program improvement in organizations working at community, state, and national levels.
Our team is comprised of senior-level staff. Our diverse expertise offers clients a range of methods to answer important, real-world questions and support program and system improvement as the work unfolds.
We support world bettering programs, policies, and systems so they can do the most for good. These include non-profit organizations, foundations, government agencies, universities, and communities primarily in the fields of health promotion, prevention, and education.
We believe we have a role as evaluators to work towards and in ways that promote social justice. We conduct our work in ways that support the unravelling of systemic oppression and contribute to equity. By equity, we mean structures and systems that are fair and just. We adhere to principles of social justice and guidance from the Equitable Evaluation Initiative.
How We Work
Our style is collaborative. We partner with our clients to craft and implement evaluation plans. We focus our energies on timely, accurate, actionable results that measurably benefit the communities our clients serve.
Our plans are responsive. Especially when you’re helping people, you must be agile. Goals change. Contexts change. We encourage rigorous, multi-method approaches that emphasize inclusiveness and a cultural fit.
Our products are shareable. We ally with our clients to ensure our work together engages stakeholders, fosters evaluation use, and inspires program improvement.
Our results are clear and actionable. We answer your key questions and help identify future directions. We take the details and weave them into a full rich story.
